Set Minimum Data Length
This sets the minimum threshold number of bytes required to form a packet in transparent
mode. The radio will wait until the data transmit delay elapses before sending a data
packet with less than this number of bytes. Can be used to keep short, intermittent
transmissions contiguous. In packet modes, the length parameter in the data packet will
override this value (See Section 3.1). This value is subject to the maximum data length
even in packet mode. See Get Maximum Data Length below.
Get Maximum Data Length (remote only, read only)
This parameter indicates the largest number of bytes that a remote will transmit per hop,
based on the size of the slot it has been allocated by the base. In general more remotes
mean less data can be transmitted per remote. By reading this parameter and dividing by
the hop duration, the remote's data rate capacity can be determined. Attempting to send
protocol mode packets longer than maximum data length will result in the packet being
discarded without being sent. See Section 2.3.3 on the tradeoffs between hop duration
and data length.
Set Maximum Number of Remotes (base only)
This parameter limits the number of remotes that can register with a given base. The
default is 62 remotes which is the maximum number of remotes that can be registered
with a base at one time. This command is useful when used in conjunction with global
roaming for load balancing when base stations are collocated. It is also useful to assure a
minimum remote throughput.
Set Packet Attempts Limit
If ARQ Mode is set to 0, sets the number of times the radio will attempt to send an
unsuccessful transmission before discarding it. If ARQ Mode is set to 1, it is the number
of times every transmission will be sent, regardless of success or failure of a given
attempt. When this parameter is set to

FFH
, RF flow control mode is entered for
transmissions from the radio (See Section 2.3.4). This mode can be entered for one or
both radios in a point-to-point system. When used in a point-to-point system the

wu
parameter should be set to 1. Using this mode in a point-to-multipoint system will stop
transmissions to all radios when any one radio has a full buffer or if the base radio
attempts to send data to a remote that has recently (<7 seconds) left the range of the base.
Set Data Transmit Delay
When used in conjunction with the minimum data length parameter, this sets the amount
of time from the receipt of a first byte of data from the host until the radio will transmit in
transparent mode. Default is

When used in conjunction with the minimum data length parameter, this sets the amount

transparent mode. Default is
00H
which causes transmission to occur without any delay.
When a host is sending a group of data that needs to be sent together, setting this
parameter will provide time for the group of data to be sent by the host before the radio
transmits. If the length of data to be sent together is longer than the time slot can send,
the data will not be sent together but will be broken up over multiple hops. The length of
time the radio will wait is equal to the specified value times the hop duration.
